Title: Duplex transmission
IPC: H04B3/23
Filed: 1980-06-20
Abstract: An echo canceller for a full-duplex carrier modulation transmission system terminal. The echo canceller includes a digital time-domain complex transversal filter with controlled weighting coefficients and an offset equal to a submultiple l of a Baud period DELTA related to a rate at which a stream of complex symbols is received at the input of the filter. These complex symbols include complex symbols outputted by a coder of a transmitter of the terminal at the rate l/ DELTA interleaved with l-1 null symbols. The transversal filter output is connected to a digital modulator operated at the transmitter carrier frequency with instantaneous values updated at intervals equal to the Baud period to generate a passband echo copy signal. The invention is of particular benefit in transmission systems in which the product of the transmission carrier frequency and the Baud period is an integral multiple of l/4, as digital implementation of the modulator is then extremely simple.

Title: Ceramic composite bodies
IPC: C04B35/58
Filed: 1988-12-12
Abstract: This invention relates generally to a novel method of manufacturing a composite body. More particularly, the present invention relates to a method for modifying the resultant properties of a composite body, by, for example, minimizing the amount of porosity present in the composite body. Additives such as TaG, ZrC, ZrB2, VC, NbC, WC, W2B5 and/or MoO2B5 can be combined with a boron carbide material (2) which is thereafter reactively infiltrated by a parent metal (3). The composite body comprises one or more boron-containing compounds (e.g., a boride or a boride and a carbide) which is made by the reactive infiltration of molten parent metal (3) into the boron carbide mass (2). Particular emphasis is placed upon modifying the properties of a ZrB2-ZrC-Zr composite body. However, the methods disclosed in the application are believed to be generic to a number of parent metals and preform materials.

Abstract: A shock absorber is electrically adjustable in a way to permit adaptation of the absorption to the type of road surface. The absorber comprises a cylinder with damping fluid, a piston with piston rod (2) displaceable in the cylinder, a sleeve (7) disposed in the piston and having two or more openings or series of openings (9, 10), two or more duct systems (15 to 18; 19, 20; 22 to 26) of differing damping characteristic being disposed in the piston.

Abstract: Foreliggende oppfinnelse er en fremgangsmåte for frem-stilling av en tyggegummi med et zein-belagt høystyrke-søtemiddel med forsinket frigjøring. I henhold til oppfinnelsen modifiseres zein-belegningen for å bli mykere, slik at søtemiddelpartiklene blir mindre kornete og merkbare i tyggegummien. Fremgangsmåten starter ved å blande on mengde zein, et løsningsmiddel for zeinet og en vannløselig, modifisert cellulose-forbindelse , som f.eks. hydroksypropylmetylcellulose sammen, for å danne en modifisert zein-løsning. Mengden av det materiale som skal inkluderes er fortrinnsvis mellom ca. 5 og ca. 40 vekt%, regnet på zeinet. Denne modifiserte zeinløsning påføres et høystyrke-søtemiddel og tørkes deretter for å fremskaffe søtemiddel-partikler med forsinket frigjøring. Disse partikler tilsettes så til en tyggegummiblanding.
